Mastering Data Analysis with OriginLab: Curve Fitting, Peak Analysis & Statistics for Graduate and Doctoral Researchers

Your data is real. Is your fit?

Every year, thousands of graduate students and researchers sit down in **OriginPro** for the first time with a spreadsheet of hard-won experimental data and no idea where to begin. Origin's own documentation is thorough but scattered, and generic statistics textbooks teach the math without ever opening the software. **Mastering Data Analysis with OriginLab** closes that gap — a practical, rigorous guide to curve fitting, peak analysis, and statistics in Origin and OriginPro, written for the researcher who needs to move from raw data to a defensible, publication-ready result.

This is not a feature-by-feature software manual. It is a workflow-driven guide built around the questions that actually matter at the bench and in committee meetings: Which test should I run — and why? Is this fit trustworthy, or just a high R²? What does a confidence band actually tell me that a prediction band doesn't? How do I deconvolute overlapping peaks without fooling myself?

**Inside, you'll learn how to:**

- Run and interpret t-tests, ANOVA with post-hoc comparisons, and normality diagnostics with confidence
- Build linear, polynomial, nonlinear, and custom fitting functions — and judge them using residuals, AICc/BIC, and confidence vs. prediction bands
- Fit and deconvolute overlapping peaks with Gaussian, Lorentzian, and Voigt functions for spectroscopy, chromatography, and kinetics data
- Use global fitting to analyze multiple datasets simultaneously with shared parameters
- Automate repeat analyses with templates, batch processing, and LabTalk/Python scripting
- Produce publication-quality graphs and reports that hold up under peer review

Nineteen chapters across five parts — Foundations, Statistical Analysis, Curve Fitting, Peak Analysis, and Automation & Publishing Results — take you from importing your first worksheet to defending your last figure, with worked case studies, summary checklists, and practice exercises in every chapter. A glossary, quick-reference menu guide, and troubleshooting appendix round out the book as a reference you'll keep coming back to.

**Written for:** graduate students (Master's and PhD), postdoctoral researchers, university instructors building a course or lab-training reference, and research scientists and engineers across physics, chemistry, materials science, and the life sciences who rely on Origin/OriginPro for statistical analysis and curve fitting but were never formally taught it.

Dr. rer. nat. Aamir Manzoor holds a doctorate in the natural sciences from the Georg-August-Universität Göttingen, Germany, with a research background in quantitative data analysis and curve-fitting methodology for experimental science.
